Other objects of the invention will hereinafter readily appear. i

7 Theimprovement claimed is hereinafter fully set forth. i

a view in'longitudinal central vertical section, illustratingthe application of'theinvention to .a locomotive boiler; Fig. 2, a view partially in top plan,- and 'partiallyin horizontal section on the line II-II of Flg. 1, of the dry steam pipe and steam drier shown in Fig. 1; and, Fig. 3, a fragmentary view, partially in transverse vertical section showing a modified form of vconstruction wherein the water collected 'bythe drier is discharged: directly back into the boiler through a check valve.

In the practice of the invention, referring; descriptively to the specific embodiment thereof which is herein exemplified, the dry steam pipe 10, comprises a stand pipe section'- 11, which projects upwardly into a steam dome 12 of aboiler 13. The upper end of the stand pipe section is provided with a horizontal annular flange 14 to which is con- I iliary, not'shown', forjezgample a Stoker steam nected a casing member 15. The casing member comprises an annular horlzontal flange 16 whichis fastened to the flange 14" of the stand pipe by studs 17 and nuts 18; an

upstanding annular wall 19, concavo-convex ceptacle 20 for collectingthe water separated from the steam, which receptacle is supported centrally of the annular Wall 19, by

spaced radial bars 20a. The parts of the eas- Inthe accompanying drawings Figure 1,

deflector may] draininto the receptacleF I auxiliary pipe 31leads' fromrthe conin cross section; and a cup shaped drain re ing members are preferably preformed to-' get-her as an integral casting, but it is .within the contemplation" of the invention to form. one or more of the parts separately ifdesired; A conduit 21 leads from the receptacle 5 through the wall of the stand pipe and is pref- T may, but not necessarily, manage with p the stand pipe. To provideforthe attach ment of a deflector, the receptacle is provided {at its top with'a support 22:comprising a,-

central metal block 22a, fromwhich' radiate spaced bars 23, the outer ends ofwhich are supported by the wall of the receptaclesat the mouth thereof. The supp0rt22 is preferably cast 'as' an integral part of the casing member, but it is within the contemplation of the invention to form it separately if desired. The deflector 24 comprises an annular up,- standing wall 25, concave-convex incross section, and a cireular'base 26 which projects into the mouth of the receptacle and is se- I cured to the block 22ab a stud 27 and-nuts '28. The annular wall 25 has its lower portion projecting into the casing concentrically thereof andspaced'therefrom, and its upper portion spaced above the' top ofthe easing a and flared outwardly to project co'ncentrical-i ly beyond the'casing. This construction provides anannular passageway 29 for the pasrsag of steam'fiomthedome', h rthe "l casing, andin'to the standpipe. Theba'sej26- offthe deflector is made of less' diameter than the internal diameterof the mouth of the re- 7 ceptacle to provide a passage through which water separated from the steam by-the duitl2l through the wall of the boiler, thus enablingthe steam and water" "entering the receptacle to be utilized for operating an auxjet. It is within the contemplation of the invention to lead the pipe 31 through the wall of theboiler, at any suitablepoint,'to'a steam trap (not shown) of any 1 usual ordesired "ing withthe conduit 21, discharges the water collected in the' receptacle20 directly into the boiler to the-rearo'f'a deflector 32which extends" "downwardly into the boiler. ;*'A' 'check'valve 83, is interposed in the pipe 311;, and aotsto permit water-from the receptacle to'flow'through the pipe 31a intothe boiler, 1 C

but prevents Water in the boiler from passing up the pipe into the receptacle.

By referring to the drawings, it will be noted, that'steain in its travel from the dome 12 to the stand pipe 11 flows through the passageway 29 into contact with the concave surface25aeofgthe Wall 25-01 thedeflector on which surface the water globules in suspenf sion Will be deposited. The steam thus dried is deflected from the surface 25a to the concave surface 19a o'f'th'=casing,"fro1nwhich latter surface it is deflected into the mouth of the stand pipe. The Water deposited-on the surface 25a of the deflector flowsdownrwardr ly through the passage'30 into the receptacle r120, from which it is j drained to the outside of the-boiler bygtheconduit' 21 and the auxiliary 1 pipe 3-1 V r Whyileoneof the preferred forms of con x-struotion has been described and-shown, it is "\ObVJiOUS'that many variations in procedure, tform, arrangement, 7 and 7 construction ,of ;parts,:;may beresorted' to, and the invention, there'forais notfl-im-ited to the particular embodiment adisclosed, but includes such changes and modificationsas come ithin the spirit and-scope of the invention as set forth in the appended claims. r
